  A Systematic Approach to the Optimization of Substrate-Based Inhibitors of the Hepatitis C Virus NS3 Protease:  Discovery of Potent and Specific Tripeptide Inhibitors

  摘要：

  The inadequate efficacy and tolerability of current therapies for the infectious liver disease caused by the hepatitis C virus have warranted significant efforts in the development of new therapeutics. We have previously reported competitive peptide inhibitors of the NS3 serine protease based on the N-terminal cleavage products of peptide substrates. A detailed study of the interactions of these substrate-based inhibitors with the different subsites of the serine protease active site led to the discovery of novel residues that increased the affinity of the inhibitors. In this paper, we report the combination of the best binding residues in a tetrapeptide series that resulted in extremely potent inhibitors that bind exquisitely well to this enzyme. A substantial increase in potency was obtained with the simultaneous introduction of a 7-methoxy-2-phenyl-4-quinolinoxy moiety at the gamma-position of the P2 proline and a tert-leucine as a P3 residue. The increase in potency allowed for the further truncation and led to the identification of tripeptide inhibitors. Structure activity relationship studies on this inhibitor series led to the identification of carbamate-containing tripeptides that are able to inhibit replication of subgenomic HCV RNA in cell culture with potencies below 1 muM. This inhibitor series has the potential of becoming antiviral agents for the treatment of HCV infections.

  A novel, metal-free oxidative intramolecular Mannich reaction was developed between secondary amines and unmodified ketones, affording a simple and direct access to a broad range of 2-arylquinolin-4(1H)-ones through C(sp3)–H activation/C(sp3)–C(sp3) bond formation from readily available N-arylmethyl-2-aminophenylketones, using TEMPO as the oxidant and KOtBu as the base.

  在仲胺和未改性的酮之间开发了一种新颖的，无金属的氧化性分子内曼尼希反应，可通过C（sp 3）-H活化简单直接地获得广泛的2-芳基喹啉4（1 H）-酮。/ C（sp 3）–C（sp 3）键由易于获得的N-芳基甲基-2-氨基苯基酮形成，使用TEMPO作为氧化剂，KO t Bu作为碱。
